Swedish Researchers Show Impact Of Long-Term Vitamin D Insufficiency On Fracture Risk

April 4, 2014

Vitamin D insufficiency sustained over 5 years contributes to increased 10-year fracture risk in elderly women

A study presented today at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases shows that long-term low levels of vitamin D intake are associated with higher 10-year fracture risk in elderly women.

Vitamin D insufficiency in seniors has been shown to contribute to increased risk of osteoporotic fractures. Previous studies have used single vitamin D measurements to investigate effects on bone. However, in elderly women, relatively little is known about the effects of long-term vitamin D insufficiency on bone health.

The study by Swedish researchers used sequential assessment of serum vitamin D to determine if sustained hypovitaminosis D in elderly women leads to increased 10-year fracture incidence.

Study participants at baseline were 1044 Swedish women, all aged 75, with 715 attending at the 5-year follow up. Serum 25-hydroxyvitamin D (25OHD) levels (nmol/l) were classified as low (<50), intermediate (50
